Silver has two naturally occurring isotopes. Find the percent abundances of 107Ag and 109Ag given the atomic mass of Silver = 107.868 amu, the isotopic mass of 107Ag = 106.9051 amu, and the isotopic mass of 109Ag = 108.9045. (Hint: The sum of the fractional abundances is 1. If x = abundance of 107Ag, then 1 - x = abundance of 109Ag.)
The equilibrium amounts would stay the same the equilibrium would shift to the right making more reagents the equilibrium would shift to the left making mroe reagents the equilibrium would shift to the right making more products the equilibrium wo..
Use the balanced redox reactions and the standard cell potential to predict the volume of hydrogen gas (at STP) required each month to generate the electricity needed for a typical house. Assume the home uses 1600kWh of electricity per month.
